AUTOMOBILE-MOTOR-VIBRATION ELIMINATOR.

Application filed July 17,

It is well known that the motors of a number of makes of automobiles, particularly the lighter machines, have an excessive amount of vibration, which is not only deterimental to the motor structure, the chassis frame and the body structure, but is very annoying to occupants of the machines. It is to overcome this objectionable motor vibration that my present invention isdesigned, the construction being such that it is applicable to a number of makes of machines.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a diagrammatic top plan view of a portion of an automobile chassis showing the application of my invention.

Fig. 2 is a sectional view as indicated by line 2-2 of Fig. 1. 1.

Figure 3 is a detail elevation looking in the direction indicated by line 3-3 of Fig. 1.

Figure 4 is an enlarged vertical sectional view substantially on line 4-4 of Fig. 1.

Figure 5 is a horizontal sectional view approximately on line 55 of Fig. 4.

Figure 6 is a detail sectional view showing a different manner of connecting the vibration eliminator with the motor.

In the drawing above briefly'described, M designates an automobile motor mounted in the usual manner upon a chassis frame which includes parallel sidebars B, commonly formed of channel metal.

To hold the motor M against excessive vibration, I may use any desired number of the devices to which this application is devoted, each device including a longitudinally elastic brace which is preferably formed of upper and lower sections 1 and 2 in the form of rods. Novel means are provided for connecting the inner ends of the brace sections 1 and 2 for connecting the upper end of the upper section to the motor, and for connecting the lower end of the lower section to the chassis frame. In the preferred form of construction, a sectional cylindrical casing 3 is carried by the lower end of the brace section 1, the upper end of said casing preferably having an opening 4 into which said upper brace section is threaded, a lock-nut 5 being preferably provided on said section to 'bind' against the upper end of the casing. The lower end 1924. Serial in. 726,576.

of the casing 3 is closed and is formed with a central opening 6 throu h which the lower brace section 2 passes s idably, the upper end of this brace section being provided with a washer 7 and nut 8 or with any other desired form of abutment to engage the upper end of a coiledcompression spring 9 which is housed within the casing 3 and contacts with the lower end wall thereof. This spring exerts its force to constantly place strain upon the upper and lower brace sections 1 and 2, tending to draw them toward each other.

I may connect the upper ends of the elastic braces with the motor M in numerous ways, two of which are shown. Extending across the rear end of the motor head, I have shown a metal strap 10 which is provided with openings to receive two of the usual bolts or the like I which attach the motor head to the block. The ends of this strap are directed downwardly as indicated at 11 and formed with openings engaging eyes 12 at the upper ends of two of the brace sections 1. In a great number of motors, it is possible to use the strap 10 at the rear end, but at the front end this cannot be done, and I therefore prefer to provide a pair of inverted L-shaped attaching members for use at this location, each member having a horizontal portion 10 to rest on the motor head, and a downwardly extending portion 11 to which one of the brace sections 1 is connected, by means of the eye 12. The portion 10 is formed with an opening to receive one of the bolts 6, and preferably an arched metal abutment 13 is secured to the lower side of said portion 10 and the inner side of the portion 11 to abut the outer side of the motor head,

as shown in Fig, 3, thereby efiectively bracing the portions 101'1.

For connecting the lower ends of the brace sections 2 with the chassis bars B, I prefer to use clamps which are held in op erative position by the upward strain or pull of the elastic braces. The preferred form of construction is illustrated more particularly in Figs. 2, 4 and 5. In these views, a plate 14 is provided to contact with the lower side of the chassis bar, said plate being channeled to receive said bar, as indicated at 15. This plate is provided with two pairs of downwardly projecting lugs 16 and 17. and an arched clamping lever 18 is fulcrumed near its lower end at 19, be-

tween the ears 16, the upper end of this lever being adapted to overlie the lower flange of the bar B. A second lever 20 which is preferably of the U-shape shown, is fulcrumed at 21 between the ears 17 and at the end of this lever remote from its fulcrum, is pivoted at 22 to the lower end of the brace section 2. Adjacent its fulcrum, the lever 20 is provided with a cam 23 engaging the lower end of the lever 18, so that the upward pull on the lever 20 eaerted by the elastic brace, will cause said cam to hold the lever 18 in clamping position.

In Fig. 6, a nut 25 is shown having an integral stud26 on its upper end. This nut is adapted to be threaded on the upper end of a cylinder head stud 27, in place of the usual nut, and any suitable number may be used for connecting the attaching members of the braces to the motor.

Any desired number of the devices may be used and they may be installed at the most advantageous points, and it will be seen that they will be very desirable and efiicient as vibration eliminators. overcoming a number of objections heretofore existing.

- As excellent results may be obtained from the details disclosed, they may be followed if desired, but within the scope of the invention as claimed, numerous modifications may be made.

I claim:

1. The combination with a chassis frame and a motor supported between and rigidly secured to the side bars thereof; of a plurality of longitudinally elastic members at each side of the motor, independent of the motor supporting means said members inclining from said side bars to the motor and being secured to both said bars and motor.

2. In a vibration eliminator for an automobile motor, a brace member, means for anchoring the lower end thereof to the automobile chassis frame, the upper end of said brace member having a horizontally directed portion formed with an opening, and a nut adapted to be threaded on one of the usual cylinder head bolts of the motor, said nut having an upstanding stud receivable in said opening to connect the upper end of the brace with the motor.

3. A vibration eliminator for automobile motors comprising a brace adapted for connection at its upper end to a motor, and a clamp having relatively movable jaws adapted to clamp a chassis bar therebetween to connect the lower end of said brace to a chassis frame. said clamp having a movable jaw-applying member connected to the brace and adapted to be held in operative position by longitudinal strain on said brace.

4. A vibration eliminator for automobile motors comprising a plate channeled to receive the lower side of a chassis bar, an arched clamping member fulcrumed to said plate to contact with the upper side of a portion of the chassis bar, a lever fulcrumed to said plate and having a portion contacting with said clamping member to hold the latter in operative position when said lever is held in one position, and a brace connected at its lower end to said lever for bolding it in said one position, the upper end of the brace being adapted for connection with a motor.

In testimony whereof I have hereunto ailixed my signature.
